118 List of Functions
Test Outputs
Item Description
Any of the following modes can be selected to accomodate the connected external device.
Test Output Mode
Not used - An external device is not connected.
Standard output - The output is connected to a standard device.
Pulse test output - A contact output device is connected and used in combination with a safety input.
Power supply output - The power supply terminals of a safety sensor are connected.
The voltage supplied to I/O power (V,G) is output from the test output terminal.
Muting lamp output (terminal T3 or T7, depending on module type) - An indicator is connected.
Unit is turned on to detect broken lines in an external indicator..
Output Status After A selection to hold or clear the previous value when a communication error occurs is available.

Safety Output
Item Description
Any of the following Safety Output modes can be selected.
Output Channel Mode
The consistency between signals on two channels can be evaluated.
Dual Channel Setting
Either of the following settings can be selected for 1791DS-1791DS-IB8XOB8 and 1791DS-IB4XOW4.
Dual-channel is the only setting for 1791DS-IB8XOBV4 and 1732DS-IB8XOBV4.
Output Error Latch Time A safety output error will be held for a minimum of this amount of time. This time should be set to be sure that
the safety controller recognizes the error. (0...65,530 ms, in increments of 10 ms)
Short-circuit Protecton Supported.
Overcurrent Detection Supported.
Publication 1791DS-UM001H-EN-P - April 2009
• Not used - External output devices are not connected.
• Safety - When the safety output is ON, the test pulse is not output (remains ON).
• Safety pulse test - When the output is ON, the test pulse is turned OFF momentarily (see page 27 for
timing). Using this function, short-circuits between output signal lines and the power supply (positive
side) and short-circuits between output signal lines can be detected.
• Single channel - used as single channel.
• Dual channel - when both channels are OK, outputs can be turned ON. If an error is detected on one of
the channels, the other channel is also turned OFF.
